Cranberry juice is a tart beverage made from the fruit of the cranberry plant, which is native to North America. It is often enjoyed for its refreshing taste and is commonly used in cocktails, smoothies, and as a standalone drink. The juice is rich in vitamins, particularly vitamin C, and contains antioxidants that may provide health benefits. Many people consume cranberry juice for its potential role in preventing urinary tract infections (UTIs). The juice contains compounds called proanthocyanidins, which may help prevent bacteria from adhering to the urinary tract walls. However, it is important to choose unsweetened varieties to maximize health benefits.
